+
+ Define the "identifier" of a symbol.
+ Symbols may have several string representations, for instance if they
+ have an alias. What I call its "id" is a string that can be used as
+ an identifier. May not exist.
+
+ Currently the symbols which have the "tag_is_id" flag set are those that
+ don't have an alias. Look harder for the id.
+
+ * src/output.c (is_identifier): Move to...
+ * src/symtab.c (is_identifier): here.
+ * src/symtab.h, src/symtab.c (symbol_id_get): New.
+ * src/output.c (symbol_definitions_output): Use it to define "id"
+ and "has_id".
+ Remove the definition of "tag_is_id".
+ * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
+ "tag_is_id" were used to produce code.
+ We still use "tag" for documentation.
